colonic diverticula

What are colonic diverticula?

Colonic diverticula are protrusions of mucosa and submucosa through areas of colonic wall weakness primarily where the end arteries perforate the colonic wall (on the mesenteric side of the antimesenteric taeniae). The diverticula protrude into the pericolic fat, separated from the pericolonic fat by a thin layer of longitudinal muscle. Diverticulum is the singular form; diverticula is the plural form. “Diverticuli” and “diverticulae” are incorrect plural forms.
